FORMULA OF TRIANGLE AREA WITH A KNOWN ANGLE
Mathematics
Cambridge IGCSE Test (0580 m16 qp 32)
Answer:
Where a and
b are adjacent sides of angle c. This formula could be applied for any triangle
(scalene, right or isosceles triangle).
Area of Triangle
= 1/2 a b sin c
= 1/2 × 27.6 × 22.3 sin 25°
= 130.1
Area of Triangle
= 1/2 a b sin c
= 1/2 × 27.6 × 22.3 sin 25°
= 130.1
So the area of triangle is 130.1 cm square.

Based on the formula area of triangle with a known angle.
Where a and b are adjacent sides of angle c. This formula could be applied for any triangle (scalene, right or isosceles triangle).
= 1/2 a b sin c
= 1/2 × 290 ×340 sin 30°
= 24650 metre squares
So, this Mesothelioma attorney’s triangular land area is metre square.
